Rhododendron spp.
shrubZones 5–9Spring-blooming shrub with masses of flowers in every color from white to deep red. Evergreen and deciduous varieties available. Thrives in acidic, well-drained soil.
Apply fertilizer for acid-loving plants after flowering. Avoid lime-based fertilizers that raise pH.
Shape azaleas right after flowering. They set next year's buds in summer, so late pruning removes blooms.
Keep 2-3 inches of pine bark or pine needle mulch to maintain acidity and protect shallow roots.
Ensure plants are well-hydrated going into winter. Evergreen azaleas lose moisture through leaves all winter.
